Unlike other passenger jets, Concorde needs to be streamlined like a bullet to allow it to fly at supersonic speeds.Concorde lands and takes-off with a very high angle of attack; this is due to the way that the delta wing produces lift at low speeds. At these high angles of attack, a fixed streamlined nose would completely obscure the runway, on landing the available view to the pilot would be only about 5 degrees. Therefore the engineers designed a drooping nose which incorporates a streamlined protective visor, one that could be configured during the different stages of flight.
